MARTIN WILLIAM MOORE, or srRINGrIEIiJ', ILLINOIS, AssIGNOR ,or ONE-THIRD 'ro GEORGE OONLIsK ANnoNE-THIRD TO JOSEPH-LOPEZ, or sIfaINGrIELD, ILLINOIS.,

@MYLENE-LAMP,

- To all whom it may concern:

Be it known that I, MARTIN 'WILLIAM MOORE, a citizen of the United States, residing at thecity of Springfield, inthe county of Sangamon, and in the State of Illinois, have invented a new and useful Improve ment in Acetylene-Lamps, of which the following is a specification.

This invention relates to lamps for generating and burning acetylene gas.

The general purposes of the invention are to provide a lamp of simple construction, o f low first cost and effective inoperation.

More specificpurposes of the invention are: 'to provide means for supplying water in controllable quantities Within the carbid box; means for distributing the water in the mass of carbid; means for filtering thegas; and means to prevent accidental closing of the valve controlling the water supply.

With these ends in view my invention consists in the novel features of construction and combinations of parts shown in the annexed drawing, to which reference is hereby made and hereinafter particularly described and finally recited in the claim.

Similar reference letters and characters designate like parts in the several views.

Figure l is a Vertical axial section through the lamp; Fig. 2 is a top plan of the lamp; and Fig. 3 is an enlarged detail of the valve.

The lamp body is of sheet metal and comprises a water reservoir A and a carbid box IS, connected by a screw U in the usual manner. A perforated sleeve F occupies a vertical position in the carbid box B in line with the tube E. The lower end of the sleeve F fits snugly around a central boss R pressed in the metal of the bottom of the box and the boss prevents displacement of the sleeve. The sleeve is kept in'place on theboss by the friction ofthe parts and may be readily removed for cleaning the sleeve.

Tater percolates through the small openings of the sleeve F," into the mass of carbid C. the parts A and B, Prevents leakage of gas or water. Ascreen t), of i'ine woven wire or other suitable retlculate material, is supported in a horizontal posit-ion on the tube E,

below the diaphragm or, and above the upper end of the carbid box. Filtering material, such as cot-ton iber,-P fills the 'space between the diaphragm and the screen C. so

that vthe gas generated in the carbid box and lpassing through lthe filtering material 'will e dried and purified before it reaches the lburner H. 'At the upper end of the reservoir is an opening c3, 'through which water 1s introduced lnto'the" reservoir. A

cap M, covers the opening ttl-and is mount- 'ed to turn on a hinge Q, ont-he upper 'end of the reservoir. A hook J, securedon the outer wall of the reservoir, 'serves as a handle, or as a. means for su porti-ng the lamp on a suitable support, suolil as the cap of the user. An inclined pipe G, 'covers an opening a, in the diaphragm and extends through the Outer wall of the reservoir'and has at its upper end a burner H of the usual construction. ,A reflector I, secured on the reservoir` A, surrounds4 the burner H and reflect-s the lightvthereof. A tube E, open at its'upperA end, is fixed centrally in a vertical position on the dia--V phragm a, of the reservoir A, and extends upwardly through the central opening al in the top 4of the reservoir, and extends downwardly into the perforated sleeve F, and has at its lower end a small opening T, through which the water drips into the perforated sleeve and thence percolates to the mass of carbid C. An inner tube D, closed at-its upper end, fits snugly within and is adapted to turn in the tube E. The tube E has a port c, in the same pla-ne with aV similar'port (l extending through the outer wall of the inner tube D.- The relation of the tubes D and E and the ports d and e are such that partial rotation of the tube D within the tube E, will serve to open or close thcports to control the supply of water entering through the tube D.

A handle K, is fixed on the upper end of .'the tube D andextends under and. may be turned in contact with a guard L, on top of the reservoir A, so that the guard will hold the handle in diiferent positions, accoi-ding to the degree of rotation of the 1nner tube D, to` open o'i' close the ports d and c; and will prevent withdrawal of the tube D from the outer tube E. The guard Il also serves to keep the tube D in such posi-- tion that the ports d and c always occupy7 the saineI horizontal plane. The handle Ix is in such position on t-he tube D that when thev 'parte d and c are completely openV the hancle will be adjacent to the free end of the guardfL and 'when the handle is turned to cause complete closing of the ports the handle will be adjacent to the leg of the ard; and'. intermediate positions of the handle will indicate to the user the different' with the .reservoir A and a sufficient quam. tity of water will be placed in the reservoir.' V When the ports d and e are closed there will' -not be any fiowio Water from the reservoir Ainto. the carbid box ,but upon turning the inner tubeD, by means of the handle' K, to open the portsd and e to the desired extent,

i a perfectly controlled supply. of water will pass throughthe tube D, into the lower part of the tube E, and thence through the opening T, into lthe perforated. sleeve F and thence it will 4seep into the mass of carbid and cause the generation of gas, which will pass through the ltering material P, to the burner H. i V

Having fully described 'my invent-ion what I claim as new and desire to secure by Letters Patent is:

In a lamp, the combination .of a carbid box, a detachable perforated sleeve extending upwardly xvithin the box, a reservoir detachably connected with the carbid box, a firstV straighttube openat both ends, secured centrally on the reservoir and extending downwardly into the sleeve within the box 'and having a port extending. through the wall of said tub'e,"a complemental rotative straight Water-control tube closed at its upper end and gaged `for gas-tight contact. with the inner vvall of the outer tube along the entire length of the inner tube and having a port extending through the Wall of the inner tube in the plane of the port ofthe outer tube, a radial handle on the inner tube adapted to turn the tube to vary the openingof the portsthrough the Walls of the outer and inner tubes to admit Water into the inner tube to drop therefrom directly into the central sleeve Within the carbid box, andan immovable guard on the reservoir adapted to4 permit horizontal movementof thehandle and contacting with the handle to prevent .upward lmovement of the inner tube, to keep the port of the inner tube in -the plane of the port of the outer tube.
